Firstly, assess what the core functionality of your solution is; what benefit is it giving your users? What features are the most important to them to become paying users?
Once you know your core offering, you can supplement its functionality through using ready-made products, designed to do a set task.
You need to add payment facilities in your app? Don’t build it from scratch, use a ready made option like Stripe or Chargebee.
You need to offer users flexible dashboards? There are tools you can include in your product that will allow you to launch the feature in a fraction of the time.
Your customers want to be able to integrate your tool with their business software? You can offer them that functionality from within your application through using an embedded iPaaS, so they can be created and deployed using low-code tools – so your developers can focus on building out your core application’s functionality.
